Does Downloading PowerPoint Slides Before the Lecture Lead to Better Student Achievement?: Reply
Get PDFThis reply responds to a comment by Cannon (2011) that opens the debate on consistency of the effect of downloading PowerPoint slides before lectures on students’ exam performance. Cannon (2011) points out potential endogeneity problems in Chen and Lin (2008) and attempts to explore the unconditional mean effect of downloading PowerPoint slides for the full sample. In this reply, we firstly argue that the estimates in our original article are consistent since the effect of interest is the “conditional†treatment effect but not the unconditional mean effect. We provide explanations for our rationale of estimating the “conditional†treatment effect. Secondly, we propose a modified downloading variable to replicate Cannon’s analysis. Our results suggest that downloading PowerPoint slides before the exam does not produce a significant effect on absent students’ exam performance which is different from the results in Cannon (2011). Our analysis does support Cannon’s argument that students fixed effects are different across different attendance status.

An investigation of Fang-ming Chen\ue2s discourses on nation and liberalism
No full textAfter the end of martial law in late 1980s, the political discourse by Fang-ming Chen, one of the proponents of Taiwan\ue2s nation building, has been taken as an indicator among Taiwan\ue2s Pan- green group. While Chen has self-reported as an liberalist, how could he remains a die hard nationalist? How did he deal with the contradiction between liberalism and nationalism? Or the declaration and practice are two different things. This thesis departs from the statement that Chen is a classic liberalist, follows, as well as does detailed reading of the content of his personal life, observes the ingredients of liberalism which have been instilled into his life to cultivate his thought of liberalism. This thesis also explores Chen\ue2s level of liberalism. Is it a deep belief, or just a mean of power
struggling? The author deeply believe that as a belief, liberalism is a goal deserved for seeking without regrets, while as a mean, liberalism is disposable.
To examine the essence of Chen\ue2s thought of liberalism, the author puts emphasis on analyzing Chen\ue2s discourses on Taiwan nation, Taiwan independence, transitional justice as well as
Cross-Strait relations. The relation between Chen\ue2s related political discourses and his perspective of classic liberalism is intriguing.
Even though Dworkin\ue2s take of liberalism stresses precarious republicanism, public will and positive liberty rather than individual
liberty, will and negative liberty, scholars still regard him as a liberalist according to his way of discussion, not the nature of the object. Since Chen is neither a constructor nor an assistant of theory of liberalism, for the author to prove or disprove Chen\ue2s stand of liberalism is to examine his discourses and practice. Is Chen
become more of liberalism or less of it? From the spirit of liberalism, any construction should be examined by time, including the author\ue2s
argument. Whether Chen could become a liberalist as declared by himself has become the battle inside him
Revision of genus Zele Curtis (Hymenoptera, Braconidae, Euphorinae) from China, with description of nineteen new species
No full textZele Curtis is a braconid parasitoid wasp genus within the subfamily Euphorinae (Hymenoptera, Braconidae), consisting of only 30 species worldwide. The Chinese species of the genus Zele are revised and 29 species are now recognised, including 19 species new to science: Z. aquilus Fang, van Achterberg & Chen, sp. nov., Z. carinatus Fang, van Achterberg & Chen, sp. nov., Z. confusus Fang, van Achterberg & Chen, sp. nov., Z. cristatus Fang, van Achterberg & Chen, sp. nov., Z. curvatus Fang, van Achterberg & Chen, sp. nov., Z. curvinervis Fang, van Achterberg & Chen, sp. nov., Z. densipunctatus Fang, van Achterberg & Chen, sp. nov., Z. extensus Fang, van Achterberg & Chen, sp. nov., Z. fulgidus Fang, van Achterberg & Chen, sp. nov., Z. fuscatus Fang, van Achterberg & Chen, sp. nov., Z. impolitus Fang, van Achterberg & Chen, sp. nov., Z. inclinator Fang, van Achterberg & Chen, sp. nov., Z. irregularis Fang, van Achterberg & Chen, sp. nov., Z. petiolatus Fang, van Achterberg & Chen, sp. nov., Z. rugulosus Fang, van Achterberg & Chen, sp. nov., Z. sculpticoxis Fang, van Achterberg & Chen, sp. nov., Z. shaanxiensis Fang, van Achterberg & Chen, sp. nov., Z. syntomus Fang, van Achterberg & Chen, sp. nov., and Z. vacatus Fang, van Achterberg & Chen, sp. nov. 31 barcode region sequences of mitochondrial cytochrome c oxidase I (COI) from the genus Zele were obtained and combined with 102 sequences from BOLD. They were used to validate new species and to get an indication of similarity among species. Three species are reinstated: Zele peronatus (Shestakov, 1940), Z. romani (Fahringer, 1929), and Z. rufulus (Thomson, 1895). In addition, an identification key for the Zele species recorded in China (plus one expected species) is provided
